Differences by sex, ear, and sexual orientation in the time intervals between successive peaks in auditory evoked potentials

► Time intervals between peaks in the auditory evoked potential (AEP) were calculated. ► Some interpeak intervals differed by sex, ear, and sexual orientation. ► Head size was not a likely contributor to the differences in interpeak intervals. ► Use of oral contraceptives did not affect the interpeak intervals. ► Correlations between ipsilateral intervals were small; those between ears moderate
